Shipping classifications

Sodium borobydride is available as a 12% solution in caustic soda and in soHd form either as powder or pellets (3). The predominant form produced is the solution, the DOT shipping classification for which is corrosive Hquid. Forms of packaging are 18.9-L pails, 208.2-L dmms, and either tank tmck or tank car for bulk shipments. 1991 pricing for the solution form was 40.34/kg of borobydride contained. SoHd sodium borobydride, a white powder packaged in polyethylene bags in metal containers, was priced at 48.39/kg. 

Ethyl alcohol is a flammable Hquid requiring a red label by the DOT and Coast Guard shipping classifications its flash point is 14°C (Tag, closed cup). Vapor concentrations between 3.3 and 19.0% by volume in air are explosive. Liquid ethyl alcohol can react vigorously with oxidi2ing materials. Ethyl alcohol has found wide appHcation in industry, and experience shows that it is not a serious industrial poison (273—275). If proper ventilation of the work environment is maintained, there is Httle likelihood that inhalation of the vapor will be ha2ardous.

Nitroparaffins are not explosives as determined by tests approved by the U.S. Department of Transportation (DOT) for shipping classifications. However, nitromethane when sensitized by small amounts of amines can be detonated by a Number 8 blasting cap. Nitromethane is used as a fuel component in ammonium nitrate explosives. 

Nitroparaffins are not explosives as determined by tests approved by the U.S. Department of Transportation (DOT) for shipping classifications. However, nitromethane when sensitized by small amounts of amines can be detonated by a Number 8 blasting cap. Nitromethane is used as a fuel component in ammonium nitrate explosives. Nitroparaffins are used in diesel fuel to increase power output of engines. Nitropropane is completely miscible in diesel fuel, nitroethane solubility is 18 wt%, and nitromethane is only a 2 wt%. Nitromethane is used as a fuel in racing cars and in model engines. A blend of nitromethane and methanol is said to produce increased power output over regular hydrocarbon fuels. 1-Nitropropane is used as a grinding solvent for the production of aluminum powder because of its ability to displace surface moisture on the aluminum and the solvent aids in the dispersion of the aluminum powder. Nitromethane is used as a metal stabilizer for... 

Classification Societies exist to promote the safe construction of ships and to protect that condition throughout the life of the vessel. One of the tools available to shipbuilders, shipowners and surveyors that can be used to achieve these aims is Non-Destructive Examination (NDE). The intent of this presentation is to describe the application of NDE to hull structure during construction and also during periodic surveys as seen from the viewpoint of the Classification Surveyor. 

During the construction of a ship the Surveyor monitors NDE results for completeness of testing and overall quality of welding. This role includes the evaluation of checkpoints taken specifically for classification purposes but also includes the monitoring of additional checkpoints taken for quality control purposes by the builder. In the case of tankers built to LR Class since 1994 and for bulk carriers built to Class since January 1996 the Surveyor will witness the actions listed as part of the ShipRight Construction Monitoring procedure that is now mandatory. 

There are no classification requirements for routine NDE beyond thickness testing and visual inspection except for repairs, modifications or where service history has identified a specific problem in which case the Surveyors will request NDE at the same locations in similar ships. Under circumstances where visual inspection has found evidence of fatigue cracking the Surveyor can also call for NDE to assess the full extent... 

For existing ships the only NDE method nominated by classification for the detection of fatigue cracks is close-up visual inspection - although all Surveyors have the option of requesting additional NDE when warranted. The sensitivity of visual inspection is influenced by the degree of surface preparation and the level of lighting at the inspected surface - which may not always meet the level of 500 lux nominated by some NDE specifications. 

Production and Shipment. Estimated adiponitrile production capacities in the U.S. in 1992 were about 625 thousand metric tons and worldwide capacity was in excess of lO metric tons. The DOT/IMO classification for adiponitrile is class 6.1 hazard, UN No. 2205. It requires a POISON label on all containers and is in packing group III. Approved materials of constmction for shipping, storage, and associated transportation equipment are carbon steel and type 316 stainless steel. Either centrifugal or positive displacement pumps may be used. Carbon dioxide or chemical-foam fire extinguishers should be used. There are no specifications for commercial adiponitrile. The typical composition is 99.5 wt % adiponitrile. Impurities that may be present depend on the method of manufacture, and thus, vary depending on the source. 

Shipping and Storage. The DOT ha2ard classification for BENZONITRILE is "Elammable", UN No. 2224. Carbon-steel dmms and tanks may be used for storage. 

DMF can be purchased ia steel dmms (DOT 17E, UNlAl, 410 lbs net = 186 kg), tank tmcks, and railcars. On Oct. 1, 1993, new regulations in the United States were estabUshed for DMF under HM-181 the official shipping name is /V, /V- dim ethyl form am i de (shipping designation UN 2265, Packing Group III, Flammable Liquid). Formerly, it was classified as a Combustible Liquid in bulk quantities, but as "Not Regulated" in dmms (49 CFR). International overseas shipments have an IMCO classification of 3.3. 

U.S. Department of Transportation classification flammable Hquid, hazard label 3.3 DOT/UN /Na shipping number 2521, flammable Hquid. Transport by sea IMDG-code class 3.3, p. 3333, emergency sheet 3—06. Transport by rail and road RID/ADR class 3 Rn 301-31c. 

Smaller amounts of phosphoms, or elemental phosphoms-containing materials, are also shipped in 115-L (30-gal) dmms that are DOT regulated (U.S. DOT lAl or 1A2 classification) and have thick shells and special gaskets and fittings for protection. Quantities up to 0.5 kg (1 lb) are allowed for shipping in two hermetically sealed (soldered), nested cans inside a wooden box where the empty space is filled with vermiculite (U.S. DOT 4C1, 4C2, 4D, or 4F classification). AH air transportation of elemental P, both U.S. and international, was prohibited beginning in 1992.

Shipment and Storage. Liquid sulfur dioxide is commonly shipped in North America using 55- and 90-t tank cars, 20-ton tank tmcks, 1-ton cylinders, and 150-lb cylinders. Cylinders made of specified steel are affixed with the green label for nonflammable gases. The DOT classification is Poison Gas, Inhalation Ha2ard. Purchasers of tank-car quantities are required to have adequate storage faciUties for prompt transfer. 

Shipping and Storage. MSA is shipped in tank tmcks and in plastic 55-gaHon dmms or smaller containers with polyethylene inserts. The freight classification is Alkyl Sulfonic Acid, Liquid 8 Corrosive Material, UN 2586, Chemical NOIBN. 

The small amount of mixed terphenyls that are sold as such, are shipped in the form of flaked soflds in 22.7 kg multiwall bags. The U.S. freight classification is Plastics, synthetic other thanflquid, NOIBN. Like biphenyl, mixed terphenyls fall under the ha2ardous chemical criteria of the OSHA Ha2ard Communication Standard (29 CFR 1910.1200). 

The terphenyl—quaterphenyl heat-transfer medium (Table 4), sold as Therminol 75 heat-transfer fluid, is shipped in dmms, tank car, or tank tmck lots. Its U.S. freight classification is Heat-Transfer Media, NOIBN. The material does not requite a DOT ha2ardous material label, but does fall under the ha2ardous chemical criteria of the OSHA Ha2ards Communications Standard (19 CFR 1910.1200). 

Benzyl chloride is classified by DOT as chemicals NOIBN, poisonous, corrosive and a hazardous substance (100 lbs-45.45 kg). Benzal chloride is classified as poisonous and a hazardous substance (5000 lbs-2270 kg). Benzotrichloride is classified under DOT regulation as a corrosive Hquid NOS and a hazardous substance (10 lbs-4.5 kg). The Freight Classification Chemical NOI appHes. It is shipped in lacquer-lined steel dmms and nickel-lined tank trailers. Benzal chloride is handled in a similar fashion.
